36 total children
Ratio of boys to girls is: 3:1
36/4 = 9 9 children to each part of the ratio
9 x 3 = 27 total boys
9 x 1 = 9 total girls
STEP 1:
Find discounted price.
Discounted $= original $ - (original $ * % discount)
Discounted $= $75 - ($75 * 20%)
Discounted $= 75 - 15
Discounted $= $60
STEP 2:
Find discounted $ plus service fee.
Price plus fee= discounted $ + (discounted $ * service fee %)
Price plus fee= $60 + ($60 * 10%)
Price plus fee= 60 + 6
Price plus fee= $66
STEP 3:
Find % change.
% change formula= (new # - original #) ÷ original # x 100
% change= (66-75)÷ 75 x 100
% change= -9 ÷ 75 x 100
% change= -0.12 x 100
% change= -12%
***the negative indicates a decrease
ANSWER: Her ticket was less than the original by 12%.
